Wharfedale Evo 5.1 Bookshelf Speakers Lunar Grey (Pair)

The Wharfedale EVO 5.1 is the most compact speaker in the EVO 5 Series, sitting below the three-way EVO 5.2 standmount and the EVO 5.3 and EVO 5.4 floorstanders. As the only two-way design in the range, the EVO 5.1 is built for versatility — equally at home as a stereo pair in a smaller room, as desktop monitors, or as surround-channel speakers within a larger EVO 5 home cinema system.

AMT Tweeter Technology

Developed from Wharfedale’s high-end Elysian project, the EVO 5.1’s enlarged 35×70mm Air Motion Transformer (AMT) tweeter delivers increased efficiency and wider dispersion compared to its EVO 4 predecessor. Rather than pushing air like a conventional dome, the AMT’s pleated diaphragm squeezes and expands air, moving approximately four times the volume of a traditional tweeter of equivalent size. This reduces distortion and allows subtle treble detail to come through cleanly. Wharfedale’s Silentweave acoustic damping material lines the interior behind the AMT to absorb internal reflections, while the ResoFrame elastomer damper — a cog-shaped gasket fitted between the diaphragm and front plate — minimises mechanical resonances for an even purer high-frequency response.

Kevlar Mid/Bass Driver

A single 130mm black woven Kevlar cone handles the mid-range and bass duties. The long-throw driver is paired with a low-distortion motor system and low-loss rubber surround, reaching down to 46Hz at the –6dB point despite the compact 11.5-litre cabinet. Wharfedale’s ResoSeal damping technique is applied to the driver assembly, optimising the midrange response for natural vocal reproduction and reducing colouration across the frequency band.

Slot-Loaded Profiled Port

Rather than a conventional rear-firing bass port, the EVO 5.1 uses Wharfedale’s SLPP (Slot-Loaded Profiled Port) system. Exhausted air exits through a downward-firing slot integrated into the speaker’s hybrid metal-and-wood plinth, with tri-directional venting to the sides and rear. This distributes airflow evenly and reduces the port turbulence that can cause ‘chuffing’ at higher volumes. The practical benefit is easier room placement — the EVO 5.1 can sit closer to a rear wall without the bass boom that rear-ported designs often produce.

Cabinet Construction

The low-resonance cabinet is built from a sandwich of materials, optimised for the largest possible internal volume within a compact footprint. Smoothly contoured edges reduce diffraction effects around the baffle, contributing to a more open and natural soundstage. The hybrid plinth combines metal and wood elements to damp vibrations before they reach the listening surface.
